Eaton EHD2040 Molded Case Circuit Breaker

Product Description

The EATON EHD2040 is a molded case thermal magnetic circuit breaker designed for overcurrent protection in commercial and industrial electrical distribution systems. It combines thermal and magnetic trip mechanisms to guard against both sustained overloads and high-level short-circuit faults. Measuring 7.5 inches long by 5.2 inches wide by 3.6 inches tall and weighing 3 pounds, the EHD2040 is a compact and robust unit suited for panelboard and switchboard installations. Licensed electricians and electrical contractors are the primary installers of this type of protective device.

The EHD2040 is intended for use in commercial and industrial power distribution applications where reliable overcurrent protection is required. It is appropriate for branch circuit and feeder protection in load centers, panelboards, and switchboards operating within the breaker rated parameters. Its molded case construction makes it suitable for environments where durability and consistent trip performance are critical to system safety and uptime.

Key Features

• Thermal magnetic trip mechanism provides protection against both overload and short-circuit conditions
• Molded case construction offers durability in commercial and industrial environments
• Compact form factor at 7.5 x 5.2 x 3.6 inches fits standard panelboard and switchboard applications

Compatibility

Designed as an OEM-style replacement or direct-fit circuit breaker for compatible EATON molded case breaker applications. Verify panelboard and enclosure compatibility with the EHD frame series before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lockout/tagout the panel or switchboard completely before removing or installing any circuit breaker. Verify that the breaker frame, voltage rating, and ampacity match the circuit requirements before energizing. Do not exceed the breaker rated interrupting capacity for the application.
